Procedure

The title compound was prepared from (S)-6-(2-hydroxy-2-methylpropyl)-6-phenyl-3-((S)-1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propyl)-1,3-oxazinan-2-one and 4-iodo-1-isopropylpyridin-2(1H)-one following a procedure analogous to that described in Example 6 Step 1. LC-MS Method 2 tR=1.846 min, m/z=489.2; 1H NMR (CDCl3) 1.10 (s, 3H), 1.24 (s, 3H), 1.39 (d, 6H), 1.52 (d, 3H), 2.17-2.31 (m, 4H), 2.35-2.46 (m, 1H), 2.88 (m, 1H), 5.27 (m, 1H), 5.69 (m, 1H), 6.49 (d, 1H), 6.88 (s, 1H), 7.00 (d, 2H), 7.29-7.38 (m, 7H), 7.40 (d, 1H). Recrystallization from isopropyl acetate following a procedure analogous to that described for Example 37 in Recrystallization Method B afforded a crystalline solid with mp 134-139° C.
